    摘要： Disclosed is an antihalation dye and a photographic element containing such dye of the formula:

    wherein
    X¹, X² independently represents -CR⁸R⁹-, -S-, -Se-, -NR¹⁰, -CH=CH- or -O-; n is an integer of 2 or 3;
    R¹ and R² independently represent alkyl of 1 to 10 carbons or substituted alkyl of 1 to 10 carbons;
    R³ represents a ring chosen from the set consisting of aryl, substituted aryl, and a heterocyclic ring containing 5 or 6 carbons in the ring with the proviso that when R³ is aryl or substituted aryl, n must be 2.
